Python sub folder modules not able to import other subfolder modules
I have been struggling to figure out how to organize my code effectively with many modules of various types. I have a three layered folder system. The parent directory contains the main.py file which imports and runs the main code. The modules are in a subfolder called lib, and different modules are placed in further subfolders. However, when I import one module from a subfolder, that module itself fails to import modules in the same sub directory. Sorry if this is a bad question, but I cannot figure out why the import statement isn't working, and I have looked at google and stack overflow and have not found any similar problem. All advice is welcome.
Parent Directory
---->lib
|--->module_group
|module_one.py(that tries but fails to import module_one)
|module_two.py
|main.py
In main I run
from lib.module_group.module_one import Module_One
Which works until an error is handled saying that there is no such module as module two. However, when I run module_one by itself, it works fine with the following import statement.
from module_two import Module_Two
python-3.x import

Set PYTHONPATH to the directory you want to act as your root. For example, if you want to use the following code:
from lib.module_group.module_one import Module_One
Then set PYTHONPATH to the directorying containing lib. For example:
lib/module_group/module_one.py:
from lib.module_group.module_two import Module_Two
lib/module_group/module_two.py:
class Module_Two:
print('Loaded Module_Two')
Then, to run module_one.py directly and still enable it to use lib.module_group.module_two to load Module_Two, use something like:
$ PYTHONPATH="${PWD}:${PYTHONPATH}" python3 lib/module_group/module_one.py
Loaded Module_Two
